This is upstream bug http://bugzilla.kernel.org/show_bug.cgi?id=7505 where you
can see more details.

Sincerely,

Sincerely,

Please always file complete bug reports, so that searching the gentoo bugzilla
isn't a complete waste of time. Without any proper description of your issue I
can't even say whether you are seeing the same bug.

OK. Let me provide more info...

Booting the kernel gives the following on the screen:

...
Decompressing Linux...done.
Booting the kernel

and at the end there is:

Kernel alive 
kernel direct mapping tables up to 100000000 @ 8000-d000


I don't have serial console, but earlyprintk=vga produces the same output as in
http://bugzilla.kernel.org/show_bug.cgi?id=7505#c2


Sincerely,
Gour

And the crash context is identical? Please type out the RIP line and call
trace, or upload a photo.

photo of kernel hanging

Hi!

Here is the pic showing how kernel is hanging.

Sincerely,
Gour

Thanks, it is indeed the same bug. Please follow the instructions I left there.

Thanks. The patch applies cleanly and the system is up :-)

Sincerely,
Gour

Hi. As I wrote on http://bugzilla.kernel.org/show_bug.cgi?id=7505 the patch
works for me. I just wonder why a bug has been also opened on gentoo bugzilla
since it's not a bug strictly related to gentoo-sources.

Well, imho, if the kernel does not boot it is serious issue and affects the
whole ~amd64 arch, therefore...


Sincerely,
Gour

Certainly doesn't affect the whole architecture, but part of the process is
informing the distros of the bugs so that they can get involved in the
solutions, and also ensure that the solutions make their way into the -stable
tree :)
(otherwise the process of getting a bugfix into a distro kernel is
significantly longer)

fixes merged upstream

Fixed in genpatches-2.6.19-5 (gentoo-sources-2.6.19-r4)
